The Key Contents from this Module are:

Plant Cell Technology is the culture of plant seeds, organs, tissues, cells or protoplasts on nutrient media under sterile conditions.

Fundamental Ability of Plants

Totipotency: The potential or inherent capacity of a plant cell to develop into an entire plant if suitably stimulated.
Dedifferentiation: The capacity of mature cells to return to meristematic condition and development of a new growing point, followed by redifferentiation which is the ability to reorganize into a new organ

Factors Affecting Plant Cell Culture are:

Explant source
Medium composition
Genetic

Aseptic conditions
Environmental conditions

Elicitors are defined as molecules that stimulate defence or stress-related responses in plants, which results in improved biosynthesis of secondary metabolites.

The concept of cellular totipotency is inherent in the cell theory of Schleiden and Schwann (1838 - 1839), i.e. cells are autonomous; as, "every cell from a cell".


The four basic plant tissues are:

Dermal tissue
Ground tissue
Meristematic tissue
Vascular tissue

Photosynthesis is the process by which autotrophic organisms use light to make sugar and oxygen gas from carbon dioxide and water.

Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.
